Specification of Letters Patent.

Patented na -.10, 1915.

Application filed May 3, 1913, Serial No. 765,258. Renewed May 1-1, 1915. Serial'No. 27,439.

To all'whom "it may concern Be it lmown that I, EnNs'r SoI-IULZ, a subject of the Emperor of Germany, residing at San Francisco, in the county of San Francisco and State of California, have in-I vented certain new and useful Improvements in Attachments to Ruling-Machines,

cil'itating the adjustment of the finder and for retaining it at difierent positions of adjustment.

A still further object of the invention is to provide, means forpermitting movementof the line finder transversely and longitudinally, so that it may be applied to and removed from any one of a series of grooves of the ordlnary ratchet wheel used in conjunction with other elements of a ruling i 10, the sald screw 8 having a circumferenmachine.

A still further object of this invention to produce a finder of the character indicated which may be applied to ruling machines now in ordinary use without any change in the construction of any part of said machines, the said invention, by reason of its simplicity, being comparatively inexpensive to produce and maintain, and possessing advantages, due to the combination and relation of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification .wherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates a view in perspective of a fragment of a ruling machine with the invention applied thereto; Fig. 2 illustrates a perspective view of the line finder; Fig. 3 illustrates a longitudinal sectional View on the line aa of Fig. 2; and Fig. 4 illustrates a sectional view on the line b?) of Fig. 2.

the stylus holder 4. The spindle is held normally with one end projected by means of a spring 5, the said spring encircling the spindle within the housing, which spring has one end bearing against the frame, to be explained presently, and the other end against a shoulder formed on the spindle. The projecting end of the spindle has an arrow head 6 and thepointed end thereof is adapted to enter the spaces between the serrations 6 formed on the periphery of the disk D, thus making it possible for the operator to locate the arrow head between any two serrations on the said disk.

The sliding plate 4 is adjusted by. means of a screw 8 which is j ournaled in the frame tial groove 11 in which a retaining plate 11 extends so that the said screw 8 cannot move longitudinally of its axis but is held rotatably in position so that any movement due to the rotation of the said screw is communicated to the guides 12, which guides are secured to the sliding plate 4 and are seated in the casing and have a threaded aperture to receive the screw 8 whereby the rotation of the screw communicates sliding movement to the guides, and the guides in turn carry or actuate the plate 4 in order that the arrow head carried by the spindle may be moved longitudinally of the casing. The screw 8 is provided with a milled head 9, which is rotated by an operator and the said screw is held atdifierent positions of adjustment by reason of the detent 13, which is in the form of a spring anchored to an end of the casing 10. By reason of the construction just indicated, the screw cannot be accidentally turned and the arrow head will,

therefore, be undisturbed except upon manipulation of the screw. By reason of the fact that the arrow head is held normally projected, it is caused to ride over the serrated or toothed periphery of the disk D until the proper line is indicated thereby, and it follows that according to the rotation of the screw 8, the said indicator may be moved longitudinally of the casing 10 to cause the said indicator to aline with the proper groove and the engraved line with which it corresponds.

As heretofore stated, the simplicity of construction is such that the casing and the parts carried thereby may be readily applied to and adjustable in operative relation to the rotating disk for the purposes intended.

What I claim as my invention is:

1. In a ruling machine having a ratchet wheel, an indicator adapted to coact with the ratchet wheel, and means for moving the indicator over the periphery of the said ratchet wheel.

2. In a ruling machine having a ratchet wheel, an indicator, a movable member for carrying the indicator, means for yieldably holding the indicator therein, and means for communicating motion to said movable member.

3. In a ruling machine having a ratchet wheel, a casing, an indicator movable therein, means within the casing for holding the indicator normally projected into engagement with the ratchet wheel, a frame, a member slidable on the frame for supporting the casing, and means for communicating motion to said member.

4:. In a ruling machine having a ratchet wheel, a frame, a guide slidable in the frame, a plate supported by the frame, a casing associated with the plate, means for moving the guide, means for communicating the motion of the guide to said plate, and a yieldable indicator carried by the casing.

5. In a ruling machine having a ratchet wheel, a frame, a guide slidable in the frame, a plate supported by the frame, a casing associated with the plate, means for moving the guide,means for communicating the motion of the guide to said plate, an indicator in the casing, and a spring for projecting the indicator from the casing.

6. In a ruling machine having a ratchet wheel, a casing, a screw having a peripheral groove, means carried by the casing adapted to enter the said groove for holding the screw against axial movement, a guide threaded on the screw, a plate associated with the guide, a casing carried by the plate, and an indicator yieldably held in the casing.

7 In a ruling machine having a ratchet wheel, a casing, a screw having a peripheral groove, means carried by the casing adapted to enter the said groove for holding the screw against axial movement, a guide threaded on the screw, a plate associated with the guide, a casing carried by the plate, a spindle slidable in the casing, and having an indicator on its end, and a spring in the casing holding the indicator normally projected into engagement with the periphery of the ratchet wheel.

In testimony whereof I have afiixed my signature in presence of two witnesses.
